Some argue that carbon capture and storage (CCS) could extend natural gas’s role. CCS captures CO₂ at power plants and buries it underground.
- Potential: Could cut emissions from gas plants by up to 90%.
- Reality: As of 2024, global CCS capacity is under 50 million tonnes annually, compared to 33 billion tonnes of global CO₂ emissions.
- Criticism: Expensive, energy-intensive, and unproven at the scale needed.
While CCS might buy time, it cannot replace a full-scale transition to renewables.
Natural Gas in Global Energy Security
Gas provides stability—but also geopolitical risk.
- Russia–Europe crisis (2022–23): Gas cutoffs triggered record-high energy prices and exposed dependency vulnerabilities.
- Asia-Pacific: LNG imports have surged, increasing exposure to global market swings.
Renewables, by contrast, decentralize supply and reduce geopolitical leverage.
Future of Natural Gas in the Energy Transition
Looking ahead:
- Short-term: Natural gas may continue as a lower-carbon option compared to coal, especially in fast-growing economies.
- Long-term: To meet net-zero goals, natural gas use must decline unless paired with carbon capture and RNG expansion.
- RNG potential: Promising but not large enough to fully replace fossil gas.
The global energy future points toward wind, solar, hydropower, and other zero-carbon solutions.
Alternatives Gaining Ground
- Biogas & RNG: Decentralized, community-scale solutions.
- Hydrogen (Green Hydrogen): Zero-emission potential, though expensive to scale.
- Wind & Solar: Cheapest new power globally, with storage solutions expanding.
- Geothermal & Nuclear: Reliable baseload options with low emissions.
The pathway forward is diversification, not further entrenchment in natural gas.
